Absent mitral leaflets

Last edited: 4/15/2026

Overview

Absent mitral leaflets, also known as parachute mitral valve or congenitally absent mitral leaflets, is a rare congenital cardiac anomaly characterized by the absence of one or both mitral leaflets, leading to abnormal valve function and potential left atrial dilation and mitral regurgitation 1.

Diagnosis

  • Echocardiography is essential for diagnosis, revealing the absence of leaflets and assessing the degree of mitral regurgitation 1.
  • Cardiac MRI may be used to further characterize the anatomy and assess left atrial size and function 1.
  • Electrocardiography (ECG) can show signs of left atrial enlargement or arrhythmias secondary to the condition 1.

    • Management

  • Medical Management: Focus on controlling symptoms and preventing complications; includes diuretics for volume overload and anticoagulation if atrial fibrillation is present 1.
  • Surgical Intervention: Indicated for severe mitral regurgitation unresponsive to medical therapy; options include mitral valve repair or replacement 1.
  • Regular Monitoring: Essential for assessing progression of mitral regurgitation and left atrial size 1.

    • Special Populations

  • Pregnancy: Management requires careful monitoring of hemodynamic stability and potential need for intervention during pregnancy; individualized care plans are crucial 1.
  • Pediatrics: Early surgical intervention may be necessary to prevent long-term complications; timing depends on severity and symptoms 1.
  • Elderly: Consideration of surgical risks versus benefits is critical; medical management may be prioritized in high-risk patients 1.
  • Comorbidities: Presence of comorbidities like heart failure or arrhythmias influences treatment strategy, often necessitating multidisciplinary care 1.

    • Key Recommendations

  • Echocardiography should be the primary diagnostic tool for confirming absent mitral leaflets and assessing mitral regurgitation severity (Evidence: Strong 1).
  • Surgical intervention is recommended for patients with severe mitral regurgitation not amenable to medical management (Evidence: Moderate 1).
  • Regular follow-up with echocardiography is crucial for monitoring disease progression and adjusting management strategies accordingly (Evidence: Moderate 1).
